969 This option supports all of the Octeon reference boards from Cavium
970 Networks. It builds a kernel that dynamically determines the Octeon
971 CPU type and supports all known board reference implementations.
972 Some of the supported boards are:
973 EBT3000
974 EBH3000
975 EBH3100
976 Thunder
977 Kodama
978 Hikari

1643 Please make sure to pick the right CPU type. Linux/MIPS is not
1644 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1645 *not* work on R4000 machines and vice versa. However, since most
1646 of the supported machines have an R4000 (or similar) CPU, R4x00
1647 might be a safe bet. If the resulting kernel does not work,
1648 try to recompile with R3000.

1850 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1851 benefit is to increase physical addressing equal to or greater
1852 than 40 bits. Note that this has the side effect of turning on
1853 64-bit addressing which in turn makes the PTEs 64-bit in size.

1869 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1870 require workarounds. Without workarounds the system may hang
1871 unexpectedly. For more information please refer to the gas
1872 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1873
1874 Loongson 2F03 and later have fixed these issues and no workarounds
1875 are needed. The workarounds have no significant side effect on them
1876 but may decrease the performance of the system so this option should
1877 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1878 systems.

Steven J. Hillc080faa2013-10-04 16:23:28 -05002372 This is a kernel model which is known as SMVP. This is supported
2373 on cores with the MT ASE and uses the available VPEs to implement
2374 virtual processors which supports SMP. This is equivalent to the
2375 Intel Hyperthreading feature. For further information go to

3043 kexec is a system call that implements the ability to shutdown your
3044 current kernel, and to start another kernel. It is like a reboot
David Sterba3dde6ad2007-05-09 07:12:20 +02003045 but it is independent of the system firmware. And like a reboot

3082 When this is enabled, the kernel will support use of 64-bit floating
3083 point registers with binaries using the O32 ABI along with the
3084 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
3085 32-bit MIPS systems this support is at the cost of increasing the
3086 size and complexity of the compiled FPU emulator. Thus if you are
3087 running a MIPS32 system and know that none of your userland binaries
3088 will require 64-bit floating point, you may wish to reduce the size
3089 of your kernel & potentially improve FP emulation performance by
